Are there any motorbike driving schools that teach/test in English?

I'm staying in Osaka for a while with my fiancee who is from here and would like to get a motorbike license. I'm looking to get the ordinary license (Futsuu) or Large (Oogata) if it's not too much extra time/effort.

I speak almost no Japanese, so I would like to know whether anyone knows of any schools that cater to English speaking foreigners, or if no such thing exists? I am British with a normal driving license and international driving license, if that matters at all. Thanks!
